BABY JUMPER CHAIR Filed Nov. 30, 1955 HIS ATTORNEY United States Patent O BABY JUNIPER CHAIR Chester C. Skirvin, Rochester, N. Y., assignor to Trimbie, lnc., Rochester, N. Y., a corporation of New York Application November 30, 1955, Serial No. 550,002 6 Claims. (Cl. 155-20) This invention relates to a baby jumper chair with more particular reference to the type involving oppositely arranged leaf springs constituting a supporting frame upon which is mounted a tray, seat, and back, and has for its purpose to afford a simple and readily adjustable arrangement for holding the back in differently inclined positions in relation to the seat.

In a more specific aspect, the invention consists in the construction of a back frame that is detachably associated with the leaf springs of the supporting frame and can be quickly and easily attached to the leaf springs of the supporting frame in differently inclined positions, the back frame being securely held in place when so adjusted.

To these and other ends, the invention consists in the construction and arrangement of parts that will appear clearly from the following description when read in conjunction with the accompanying drawings, the novel features being pointed out in the claims following the specification.

. In the drawings:

Fig. l is a view in side elevation showing a preferred embodiment of the invention, the back and back frame appearing in a slightly inclined position in full lines and in a more inclined position in dotted lines;

Fig. 2 is a perspective view of the wire back frame removed from the chair and fabric back;

Fig. 3 is a detail perspective view, partially broken away, illustrating one of the leaf springs of the supporting frame with the back frame in locked engagement therewith;

Fig. 4 is a rear elevation, partially broken away, and

Fig. 5 is a front elevation with parts omitted.

Referring more particularly to the drawings in which like reference numerals refer to the same parts throughout the several views, the structure shown includes a supporting frame consisting of opposite'leaf springs, each having a top horizontal portion 1, a rearwardly and downwardly inclined portion 2, and a rear vertical depending portion 3 that is supported by a coil spring 4 connected to an upstanding post 5 of the base. The base is formed by a generally U-shaped frame of tubular cross section formed by side bars 6 and connecting front bar 7, the side bars terminating at their rear ends in the previously mentioned upstanding posts 5, while 8 designates a bottom or floor attached to the side bars 6 and front bar 7 of the base.

The opposite leaf springs of the supporting frame include at their front ends the bowed portions 9 which extend rearwardly at 11, thence downwardly and rearwardly at 12 and are connected with the terminal portions 13 that are fixedly attached at 14 'to the side bars 6 of the base. 15 designates resilient blocks, preferably of rubber or other suitable yieldable material, arranged between the horizontal portions 11 of the leaf springs and the bottom or floor 8, and adjustable endwise of the springs for the purpose of varying the resiliency and bouncing action of the springs.

2,735,730 Patented Mar. 19, 1957 Mounted upon the top horizontal portions 1 of the springs in any convenient manner are the tray 16 and seat 17, while 18 designates the back of plastic or other suitable fabric or flexible material connected to the seat 17 and removably mounted upon a back frame which is adjustably positionable as will now be described.

The back frame is of generally inverted U-shaped form constructed of a heavy wire or rod of suitable flexibility, and includes a top 19 and downwardly extending arms 21, that normally are in locked engagement with the leaf springs of the supporting frame, and are yieldably movable toward each other for releasing from the frame. The leaf springs are provided with slots or recesses on their inner edges as indicated at 22, located preferably toward the rear of the horizontal portions 1, and toward the top of the rear downwardly inclined portions 2, enabling the back and back frame to be positioned in locked relation to either pair of slots and thus in difierently inclined positions and in different relationships to the seat.

To accomplish this, the arms 21 of the wire back frame terminate at their lower ends in loop portions, each including a generally horizontal top positioning portion 23, a vertically spaced bottom positioning portion 24, and a connecting locking portion 25 which engages the slot or recess 22 in the adjacent spring, while the top and bottom positioning portions 23 and 24 of the loop-shaped portion lie in close proximity to the top and bottom of the leaf spring engaged thereby. Thus'when in locked position, with the connecting locking portions 25 vertically disposed in the slots 22, the arms 21 of the back frame spring away from each other toward the inner ends of slots 22, and the back frame is held securely against movement forwardly or backwardly of the supporting frame by the slots 22 which engage the front and rear surfaces of the connecting locking portions 25, while the top and bottom positioning portions 23 and 24 of the loop portions of the wire back frame engage the top and bottom surfaces of the .springs, and thus hold the back frame securely against any tilting movement in relation to the springs, maintaining the back in the selected preadjusted relation to the supporting frame. 26 designates a brace bar connecting the vertical rear portions 3 of the springs.

The back and back frame may be positioned in either the full line nearly upright position or the inclined resting dotted line position shown in Fig. l, and when it is desired to shift the back from one position'to the other, the arms 21 of the back frame are compressed toward each other sufficiently to remove the connecting portions 25 from the slots 22, and the back frame can then be shifted until opposite the other pair of slots 22, which receive the connecting portions 25 when the sides of the back frame are released and permitted to spring into the slots.

The structure shown affords a simple, practical and easily controlled arrangement that can be manufactured economically, and provides a back that is easily adapted for either a small young baby or a somewhat older child for which a more upright position in the chair is desirable, and which when adjusted to either position is held securely and safely at the desired angle.

While the invention has been described in relation to the particular construction shown, it is not restricted to the details herein disclosed, and this application is intended to cover such modifications or departures as may come within the purposes of the improvement or the scope of the following claims.

I claim:
